He sighed deeply, yawned till his jaws threatened to crack, and until he displayed a cavity even bigger than that which Geoff had compelled and into which Philip had thrust the gag with such delight. Then the German sank back into his seat again, and bade the driver, peremptorily, to drive onwards. Soon, too, heavy breathing just in front of them told the two young subalterns that von Hildemaller was sleeping again. "Rather a near thing that, eh?" grinned Philip, his head now close to his chum's, and displaying just a little more common sense and caution. "What would we have done if he had spotted us that time when he looked round?" It was Geoff's turn to smile, a meaning smile, while he stretched out one hand, balancing himself in that uncomfortable position which he had maintained throughout the night, and slowly doubled up the fingers of the other hand--fingers bursting with muscle and with tendons as strong and as elastic as steel--doubled them up slowly, in a manner which seemed to emphasize the power within them, whereat Philip sniffed and sniggered. In a moment, in fact, he realized how much Geoff had longed for another tussle with the German, how he would have almost welcomed discovery at that moment. "I know," he whispered. "I know what you'd have done, and the beggar deserves it. You'd have taken him by the neck, you'd have remembered Douglas Pasha, and you'd have squeezed the life out of his body." Of a sudden he gripped the powerful hand held out before him, gripped it and shook it with energy, while he stared hard at his chum. "Why not?" he asked. "Good idea! Why not? Why not squeeze the life out of him now that we've got him, that is, almost squeeze it out of him. There's nothing to fear, we ain't surrounded by a prison, and we'd soon clear that driver off, or, for the matter of that, force him to do our bidding. Why not grab this brutal German and squeeze him till his eyes bulge out of his head, till he's choking, till he'll be glad to give away that secret of his, till he'll beg and beg and whine to us that he'll release Douglas Pasha? Why not?"
